SOLE FITTING AND CHANNELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 474,608, dated May 10, 1892.

Application filedJuly 1, 1891- Serial No. 398,156- (No model.)

ments in machines for rounding or trimming flat soles before they are incorporated into boots or shoes, and at the same time cutting the stitch-receiving channels in said soles; and it has for its object to provide certain improvements in machines of this class looking to the increased efficiency of the machine.

The invention consists in the several improvements, which I will now proceed to describe and claim.

In the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of a portion of a'sole fitting and channeling machine embodying my invention. Fig. 2 represents an elevation of a portion of the opposite side from that shown in Fig. 1. Fig.3 represents an end elevation of the portion of the machine shown in Fig. 2. Fig. at represents a section on the line 4 4 of Fig. 3, looking downwardly. Fig. 5 represents a section on the line 5 5 of Fig. 4. Fig. 5 is a detail section on line 5 5 of Fig. 2. Fig. 6 represents a section on line 6 6 of Fig. 2. Fig. 7 represents a top plan view of the pattern employed in my improved machine. Fig. 8 represents a section on line 8 S of Fig. 7. Fig. 9 represents a view similar to Fig. 2, showing some of the parts in a different position. Fig. 10 represents a side elevation of a modification. Fig. 11 represents an end view of the same.

The same letters of reference indicate the same parts in all the figures.

a represents the pattern, which is the exact shape of the sole that is fitted and channeled by the operation of the machine, said pattern being adjustably secured to a fixed support I), which constitutes a part of the machine.

0 represents the sole to be trimmed, the same being placed upon the pattern aand secured thereto by any suitable means, such as a clamp d, substantially as shown in Letters Patent granted to Jason Smith, January 9, 1883, No. 270,498. The pattern and sole are revolved on a fixed center, while the channeling and trimming devices, hereinafter described, are yieldingly held in operative relation tothe pattern and caused to simultaneously trim the edge and channel the face of the sole, the pattern and the channeling and trimming devices being actuated by any suitable meanssuch, for example, as are shown in the patent above mentioned-myinvention relating to the channeling and trimming knives and to the devices for directly supporting and adjusting the same, and not to the means for actuating the said knives and the pattern.

6 represents the sole-trimmingknife,which is mounted upon a supporting bed or plate g, the latter beingsupported by the carrier f, substantially as shown in the patent above referred to or otherwise. The knifeeis provided witha shank 6 which is formed to rest upon the top of the plate g, and has at one end a doWnwardly-projeoting flange e which is provided with a slot 6 receiving a screw 6 which passes through said slot into the supporting-plate g.

e 6 represent bearing-screws, which are inserted in the plate g and hear at their outer ends against the inner side of the flange e the head of the screw 6' bearing against the outer side of said flange. It will be seen, therefore, that the screws 6 and e, arranged as shown, constitute a convenient means for adjusting the trimming-knife e to compensate for wear of its cutting-edge, the flange e being clamped between the outer ends of the screws 6 and the inner surface of the head of the screw 6 so that the adjustment of said screws out or in from the edge of the'plate Q will correspondingly adjust the knife 'ei The slot 6 permits the knife 6 to be adjusted laterally or toward and from the edge of the pattern 66, as will be readily seen.

The knife-supporting bed or table g is provided with a vertical standard g, projecting above the plate 9, said standard having at its upper end an arm 9 the outer end of which is directly over and in line with the trunnion 9 which is affixed to the bed or plate 9 and is fitted to turn in a socket in the carrier f.

It represents a center, which is affixed to a vertical standard 71/ and bears on the outer end of the arm 9 said center and the trunnion 9 being in line with each other, so that the ICO bed or plate g and standard g are adapted to swinghorizontally, as described in the Smith patent, above referred to.

t: represents an arm or holder, which supports the presser foot or gage j, the channeling-knife Zr, and the grooving-knife 7a, which cuts the stitch-receiving groove in the bottom of the channel formed in the face of the sole by the channeling-knife. The foot or gagej is arranged to bear on the upper su rface of the sole at a point immediately in front of the channeling-knife 7c, and is attached to the arm *6 by means of a bolt j, passing through a vertical slotj in the shank of 'said'footor gage, said slot and screw permitting the gage to be adjusted vertically. Thevertical adj ustment of the gage j. may be effected by means ofascrew 3' having a broad headj engaged with a'groove j in the shank of the gage j, said screwbeinginserted in athreaded socketin the arm 1', so that when rotated it will be moved up or down, as the case may be, and thus correspondingly move thegage The knives 7r andk' are directly attached to a slide-t", whichis supported by and ishorizontally movablenpon the arm i. said armc' having dovetailed guides-or ways 41 Fig. 3, which receive a corresponding dovetailed tongueonthe slide 11, so that the knives 7r. 75' are movable horizontally toward and from the trimming-knife e, independently of the gage j,the-latter being attached directly to the arm 2', as abovestated, said arm having no'horizontal movement. The channeling-knife 7r lias'itsshankk formed to bear on one side of the slide 2",and said-shank isprov-ided at itsupperend with arecess, which receives the eccentric head m of a screw m, which is inserted in the slide t". By rotating said screw the eccentric head is caused to adjust the channeling knife laterally by turning the shank k of said knife on a pivot le that secures-it to the slide 6', the eccentric head at bearing on the sides of the recess in said shank, as shown in Fig. 2. The groovingknife has its shank 70 pivoted at k to a block 0,'which is vertically movable in a guide or way formed for it in the slide 2', and is engaged at its upper end with the head 0 of a screw 0 (see Fig. 3,) inserted in the slide 2", said screw being adjusted vertically when rotated, and thus moving the block 0 and grooving-knife 70 up or down, as the case may be, to vary the depth of the groove cut in the channel. The shank it has a recess in its upper end receiving the eccentric-head n of a screw W, said screw by its rotation imparting alateral adjustment of the grooving-knife 7c, the adjustments of the two knives 70 and 7c being similar, so that each is movable toward and from the trimming-knife e to vary the distance of the channel and groove from the trim-med edgeof the sole. It will be seen that the pivotal connection of the shanks of the knives-k and 70, respectively, to the supporting-slide t" and the block 0 and the eccentricheaded screws engaged with recesses in the channeling.

upper ends of said shanks constitute a very simple and desirable means for'effecting the Y the standard g, and is provided with ears or gibs 1' i which are engaged with guides or ways g on the standard g. (See Fig. 6.) The vertical movability of the arm 2' enables the gagej and knives 7c k to be raised out of their operative posit-ion when it is desired to trim or round the edge of the sole without The arm t' is normally held down to keep said gage and knives in their operative position by means of a spring 19, which is mounted upon a standard g, one end of said spring being enlarged to form a hub p, which is pivotally connectedto the stand ard g by means of a screw or pivot 19 the free end of the springbearing on theupper end of the arm 1', as shown in Fig. 1. The spring 19 has sufficient force to hold the gage j and knives 7c 70' down to their work, and is at. the same time sufficiently yielding to permit said gage and knives to be raised by means of a cam-lever g, which is pivotedat q to a head 1' formed onavertical rod or standard i affixed-to the arm 2', said standard being adapted to slide vertically in a guide formed for it in-thearm 9 The lever g has one end formed as a cam (1 which bears-on the upper side of the arm 9 andis so formed that when the outer end of the lever is-raised from the position shown in Figs. 1 and 2 the cam will elevate the head t rod and arm .11 with the attachments on said armviz.,the

gage j, slide-i, and knives 70 70, this upward movement being against the stress of the spring'p, and causing the immediate elevation of the knives 7c 7t and gage above their operative positions. The stress of the spring .19 may be varied by means of an adjustingscrew p inserted in a lug 19 formed on the standard g, (see Fig. 1,) and'bearing against an car 19 formed on the rigid portion or hub of the spring.

When the lever q is raised to elevate the arm 2' and its attachments, as above described, the parts thus elevated may be retained in their elevated position by means-of a catch or button r, which is connected by a screw or pivot r to the arm g and is adaptedto be turned so that one end will project under the head i when the latter is elevated, thus preventing the depression of said head and of the arm 11 and its attachments until the button is turned to remove it from under said head.

The horizontally-movable slide t", carrying the channeling-knife 7c andgrooving-knife 70', is normally pressedforward to hold said knives at their maximum distance from the trimming-knife e by means of a springs, which is slide z" and spring 3 is to enable the knives 7c and it" to cut the channel and groove at varying distances from the edge of the sole, so that the channel may be cut farther from the edge at the shank than at other portions of the sole-edge.

To the slide 2" is connected a vertical rod or stud t, the lower end of which is affixed to a block t, mounted on a slide 15 which is movable in a guide formed for it in the bed or plate g, the forward end of said slide projecting beyond the shoulder or face g which is formed on the plate or bed g as the surface that bears on the edge of the pattern a. In the edges of the shank portions of said pattern are formed grooves a a, as shown in Figs. 2, 7, and 8, said grooves gradually decreasing in depth from their central portions to their ends, as indicated by the dotted lines in Fig. 7. The slide 7? is arranged to coincide with said grooves, and is formed to enter the same, so that when the movement of the carrierf brings the bed or plate gand slide t to the shank portion of the pattern the slide 25 will be forced by the spring 8 outwardly into the groove 0/, as shown in Fig. 2, the slide 1'' and the knives k 75 moving outwardly to the same extent, so that the knives 7s 7e are caused to recede from the trimmingknife c and thus cut the channel along the shank portion farther from the edge of the sole than elsewhere. Thus the slide 25 constitutes a guide connected with the operating-knives, and by entering the groove a, of the pattern serves to guide or hold the said knives at the proper distance from the center of motion. When the bed or plate g passes away from the grooved portion of the pattern, the slide 25 is forced outwardly by the edge of the pattern until its outer end is flush with the shoulder g, as

shown in Fig. 9, the knives 7a being thus caused to approach the trimming-knife e and cut the channel at the minimum distance from the edge of the sole. This provision for automatically varying the distance between the channel and the edge of the sole is new with me, and is a feature of much importance.

The slide 15 is preferably independently adjustable, so that when in the position shown in Fig. 2 it may project to any desired extent outside of the shoulder g To this end I form a screw-thread on the rear end of said slide, as shown in Fig. 5, and engage with said threaded portion a nut i which is connected with the block if, so that when rotated it will move the slide t endwise. The stud t, which connects the slide 6 with the slide 2", is shown as entering a sleeve 25 which is ad justably secured to the slide 1" by means of a screw i", said screw being engaged with the slide 71, so that it will rotate without moving endwise therein. The sleeve 75 has a projection or offset at one side projecting into a slot i in the slide i, said projection having a screw-threaded orifice which receives the screw i The rotation of said screw moves the slide 1" endwise in one direct-ion or the other, thus moving the knives 7c 70' toward or from the trimming-knife. The spring 8 is preferably arranged to bear on the stud t, as shown in Fig. 2, and its pressure normally holds the block 15 against the rear end of the bed or plate g, so that the studtand the sleeve t thereon becomes the standard by which the slide 41' is adjusted when the screw t is 1'0- tated.

From the foregoing it will be seen that the following advantages are secured by my invention, viz: First, the trimming-knife is capable of being readily adjusted to compensate for wear of its cutting-edge; second, the channeling and grooving knives are adaptedto be quickly thrown up from their operative position and as quickly restored thereto; third, the channeling and grooving knives are adapted to be readily adjusted laterally, first, by means of the eccentric-headed screws m and n, and, secondly, by means of the adj usting-screw t fourth, the channeling and grooving knives are adapted to automatically vary the distance between the channel and the edge of the sole. The machine is therefore capable of any desired adjustment, and the convenience of its operation is greatly increased over that of any other machines not provided with the described improvements.

In Fig. 10 I show the slide "5, provided with two channeling-knives M u, arranged to form a lip and channel on an inner sole. The knife to is formed to cut into the edge of an inner sole to form the usual upwardly-turned lip, to which (in a welted shoe) the Welt is stitched, while the knife u is arranged to cut the channel in the upper surface of the inner sole. The knife to is attached directly to the slide't" and is preferably made adjustable by means of an eccentric-headed screw and a pivotal connection with the slide 1 after the manner of adjusting the channeling-knife 7c.

The knife to is attached to a slide n movable horizontally on the slide '6 to permit the knife n to be adjusted toward and from the knife n, and thus vary the distance between the channel cut by the knife u and the bottom of the lip cut by the knife u. The slide u is adjusted by means of a screw u the head of which is engaged with a groove in said slide, while its threaded shank is engaged with a threaded socket in a boss a on the slider.

The attachment shown in Figs lO and 11 may be used interchangeably with the knives 7c and 76' and their supporting devices shown in the preceding figures.

It is obvious that the slide 2" maybe omitted in case it is not desirable to give the channeling and grooving knives the described automatic movement from and toward the trimming-knife, the said knives being in such case supported directly by the arm 1'.

I claim- 1. In asole fitting and channeling machine, the edge-trimming knife 6, having a flange e on'its shank, combined with a bed or support: for. said knife, theadjustingescrew e bearing on the outer side. of said flange, and the adjustable bearing-screws e arranged. to bear, on'rthe inner side of; saidflange, as set forth.
